Check the 30m feed line, connectors, etc.  Also test it into a dummy 
load.  Although you might have some difficulty determining receive 
sensitivity, you'll notice if you get the Hi Curr indication.  Maybe the 
problem isn't actually in the K2!  Poor contact in coax connectors often 
looks like this.
